UNAUDITED PRO FORMA CONDENSED COMBINED

FINANCIAL INFORMATION AND NOTES

The following unaudited pro forma condensed combined financial information and notes thereto have been prepared in accordance with Article 11 of Regulation S-X in order to give effect to the merger and the related transaction accounting adjustments (pro forma adjustments) described in the accompanying notes. The following unaudited pro forma combined financial statements present the historical consolidated financial positions and results of operations of Community West Bancshares ("CWB") and United Security Bancshares ("USB") as an acquisition by CWB of USB. Under the acquisition method of accounting, the assets and liabilities of USB are, as of the effective date of the merger, recorded at their respective fair values and added to CWB.

The unaudited pro forma condensed combined balance sheet combines the historical balance sheets of CWB and USB as of December 31, 2025, giving effect to the merger (including the issuance of shares of CWB common stock pursuant to the merger agreement) as if those transactions had occurred on that date. The unaudited pro forma combined consolidated condensed statements of income for the year ended December 31, 2025 combines the historical consolidated statements of income of CWB and USB giving effect to the merger (including the issuance of shares of CWB common stock pursuant to the merger agreement) as if those transactions had occurred on January 1, 2025, the first day of CWB's fiscal year. The unaudited pro forma condensed combined financial information contained herein does not give effect to any of the financial results of CWB or USB following December 31, 2025.

The unaudited pro forma condensed combined financial information is presented for illustrative purposes only and is not necessarily indicative of the actual results that would have occurred if the merger had been consummated during the period or as of the date of which the pro forma information is presented, nor is it necessarily indicative of future results. The pro forma information includes transaction costs such as change in control payments, investment banker fees, professional fees, and contract termination costs. The pro forma costs do not include the benefits of expected cost savings or opportunities to earn additional revenue, as these are nonrecurring in nature and not factually supportable. Estimated merger costs are subject to change, and actual merger costs could differ from such estimates. The pro forma fair values for assets and liabilities are subject to change as result of final valuation analyses. The final adjustments may be materially different from the unaudited pro forma adjustments presented herein. There were no assumptions for the repurchase of shares issued in connection with the merger.

The pro forma shareholders' equity and net income should not be considered indicative of the market value of CWB common stock or the actual or future results of operations of CWB for any period. Actual results may be materially different than the pro forma information presented.

The unaudited pro forma condensed combined financial information is based on and should be read in conjunction with:

•the accompanying notes to the unaudited pro forma condensed combined financial information;

•the separate historical audited consolidated financial statements of CWB as of and for the year ended December 31, 2025, and the related notes, included in CWB's Annual Report on Form 10-K for the year ended December 31, 2025; and

•the separate historical audited consolidated financial statements of USB as of and for the year ended December 31, 2025, and the related notes, included in USB's Annual Report on Form 10-K for the year ended December 31, 2025.

Note 1 - Basis of Presentation

The unaudited pro forma condensed combined consolidated financial statements and explanatory notes have been prepared under the acquisition method of accounting for business combinations. The unaudited pro forma condensed combined balance sheet as of December 31, 2025 gives effect to the merger as if it had occurred on that date. The unaudited pro forma condensed combined statements of income for the year ended December 31, 2025 give effect to the merger as if it had become effective on January 1, 2025. This information is not intended to reflect the actual results that would have been achieved had the acquisition actually occurred on that date. The pro forma adjustments are preliminary, based on estimates and are subject to change as more information becomes available and after final analyses of the fair values of both tangible and intangible assets acquired and liabilities assumed are completed. Accordingly, the final fair value adjustments may materially differ from those presented in this document.

Note 2 - Accounting Policies and Financial Statement Classifications

The accounting policies of USB are in the process of being reviewed in detail by CWB. Upon completion of such review, conforming adjustments or financial statement reclassifications may be determined.

Note 3 - Purchase Price

Pursuant to the terms of the Merger, each outstanding share of USB capital stock was automatically converted as a result of the Merger into the right to receive 0.4520 shares of the Company's common stock, with cash to be paid in lieu of fractional shares. Each outstanding share of the Company's common stock remains outstanding and was unaffected by the Merger. As a result of the Merger, the Company issued approximately 7,922,156 shares of Company common stock.

The following table summarizes the determination of the preliminary estimated purchase consideration based on the closing stock price as of March 31, 2026.

CWB shares to be issued in merger			7,922,156
CWB stock price as of March 31, 2026			$	23.30
Common stock consideration			$	184,586,235
Cash in lieu			6,639
Cash consideration for stock options			79,239
Total consideration			$	184,672,113

Note 4 - Merger and Acquisition Integration Costs

In connection with the USB merger, the plan to integrate the operations of USB will occur in the second and third quarter of 2026. The specific details of the plan to integrate the operations of CWB and USB will continue to be refined over the next several months, and will include assessing personnel, benefit plans, premises, equipment, and service contracts to determine where CWB may take advantage of redundancies. Certain decisions arising from these assessments may involve involuntary termination of employees, vacating leased premises, changing information systems, canceling contracts with certain service providers, and selling or otherwise disposing of certain premises, and furniture and equipment. CWB also expects to incur merger-related costs including professional fees, legal fees, system conversion costs and costs related to communications with customers and others. To the extent there are costs associated with these actions, the cost will be recorded based on the nature of the cost and the timing of these integration actions in the period incurred.

Note 5 - Estimated Annual Cost Savings or Revenue Opportunities

While CWB expects to realize cost savings from the USB merger, the pro forma information, although helpful in illustrating the financial characteristics of the combined company under one set of assumptions, does not reflect the benefits of expected cost savings, opportunities to earn additional revenue, the impact of restructuring and merger-

related costs, or other factors that may result as a consequence of the merger and, accordingly, does not attempt to predict or suggest future results. Further, there can be no assurance cost savings will be achieved in the amount, manner or timing currently contemplated.

Note 6 - Pro Forma Adjustments to Combined Condensed Balance Sheet at December 31, 2025

Note 7 - Pro Forma Adjustments to Combined Condensed Statements of Income

The following pro forma adjustments have been reflected in the unaudited pro forma combined condensed statement of income for the year ended December 31, 2025. All adjustments are based on current assumptions and valuations, which are subject to change.

J. Adjustment reflects the yield adjustment for interest income on loans. The fair value adjustments for loans will be accreted through loan interest income over the estimated life of the portfolio on a level yield method, which is expected to be recognized over a weighted average life of 6.7 years.

K. Adjustment reflects the yield adjustment for interest income on investments. The fair value adjustments for investments will be accreted through investment interest income over the estimated life of the portfolio. The weighted average remaining life of the investment portfolio was estimated at approximately five years.

L. To record estimated premium amortization on the USB time deposits.

M. To record estimated amortization expense of the USB core deposit intangible asset less merger costs included in the consolidated statements of income for CWB and USB for the year ended December 31, 2025.
